It is plainly to be seen that to have analytical work of any 

 value, samples mast truthfully represent the lots from which 

 they are taken. Therefore care must be used that the samples 

 are taken from the whole and not a portion of the lot. Below 

 are a few simple directions for 



SAMPLING FERTILIZERS AND ASHES. 



If the material is in a heap, small portions, about a cupful, 

 should be taken from different parts of the pile, inside as well 

 as outside, and poured upon a paper or clean board. The small 

 pile should then be thoroughly mixed, after which a sample of 

 about one pint should be taken from it and put into a fruit jar 

 or tight tin box. If the material is in bags or barrels, a quart 

 or more should be taken from each of several packages between 

 the surface and centre, and mixed and sampled as above.
